most of the user routines are blocked (i.e. use BLAS3 in the algorithm whenever possible). Thus those are pretty straightforward to find.

Note there are also non blocked routines available in LAPACK. For example the routines xGETF2 use BLAS2 to perform the LU factorization (as opposed to the user routines xGETRF that use BLAS3). Below is a non-exhaustive list of the block / nonblock routine in LAPACK that I made. There might have some mistakes, so any contribution/correction is welcome.
